Horizontal oil-fired boiler adopts the design idea of flue gas step waste heat recovery, and the flue gas condenser is set in the tail of the boiler body, which reduces the flue gas temperature (<100℃) and improves the boiler efficiency while reducing the harmful components in the flue gas. Water tube type boiler uses well-known brand burner and reasonable furnace structure, so that the combustion is full. The composition of the exhaust gas conforms to the environmental protection index of a class of areas, and the noise is lower than the national standard.
SZS series boiler heating surface layout is reasonable, technical parameters are appropriate, the heat transfer area is surplus, so it has a certain overload capacity. SZS series steam boiler flue gas and working medium using countercurrent layout, average temperature and pressure is large, heat transfer is good, furnace volume selection is reasonable, to ensure full combustion of fuel. The series of boiler insulation materials are aluminum silicate felt and superfine glass silk cotton, the total thickness of about 200mm. This kind of thermal insulation makes the heat loss of the boiler to a minimum, the thermal efficiency is greatly improved, fuel saving, low operating cost.
Oil-fired steam boiler condenser not only absorbs a lot of sensible heat in the flue gas, but also absorbs a lot of latent heat in the flue gas, so that the boiler efficiency is higher than that of ordinary boiler. The water tube type boiler condensing waste heat recovery device adopts special acid-resistant, chloride ion corrosion ND steel, which greatly extends the service life of the boiler. The boiler adopts slight positive pressure combustion, and the furnace wall tube is a full membrane wall structure. It has a certain pressure-bearing capacity, and no smoke or air leakage will occur when operating under slight positive pressure. The boiler is a double-drum vertical installation type, with small water capacity, fuel oil as fuel, low heat storage in the furnace, low vaporization rate of water after power failure, so that the power failure protection operation is simple. The boiler is equipped with explosion-proof doors and furnace pressure monitoring devices to ensure safe and reliable operation.
The upper and lower drums of the water-tube steam boiler are equipped with manholes at the front and rear, and inspection doors are arranged at the back of the furnace and on the flue, which is convenient for maintenance. The boiler is a self-contained boiler, which not only meets the requirements of transportation size, but also shortens the installation period. At the same time, the aluminum casing and the frame are connected by bolts, which is convenient for disassembly and maintenance. The main engine, chimney and piping system of SZS series steam boiler, of which the main engine and chimney have been manufactured in the factory, and the piping valves and instruments matching the main engine have been installed at random, and the main engine and chimney can be assembled on site. Connect the air source, power supply, and water pipelines on site to start a test run. The installation cycle is greatly shortened, and the product quality can be guaranteed.
The water tube type boiler has a compact and reasonable structure design, complete auxiliary machines and advanced comprehensive technical performance. SZS series fuel oil boiler assembly and modular design, conducive to the production of large capacity boiler module, equipped with environmental protection energy-saving device, high-performance imported burner, automatic intelligent control, to ensure a high starting point in technology and quality, high quality and performance of reliability, safety. This type of oil-fired boiler adopts the unique welding technology of smoke tube and tube plate, which not only prevents the corrosion of tube gap, but also enhances the welding strength. The threaded pipe with high heat transfer coefficient is adopted to strengthen the effect of convection heat transfer, reduce the exhaust temperature and improve the thermal efficiency of the boiler.
